SHIELD FOR SPECTACLE-FRAM ES.

SPECIFICATION forming part of Letters Patent No. 422,001, dated February25, 1890. Application filed September 24, 1889. Serial No. 324,932. (Nomodel.)

To (0% whom it may concern:

Be it known that I, HARRY M. WVILSON, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Shields for Spectacle-Frames, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention has for its object the provision of an opaque shield forspectacle-frames; and among the objects in View are the provision of ashield which shall be light and inexpensive and capable of beingremovably secured and adjusted, and so arranged as to prevent theentrance of any side light usually falling upon the lenses and causing arefiection so objectionable and injurious to the eyes of the wearer.

Other objects and advantages of the invention will hereinafter appear;and the invention consists in an opaque light shield of 0011-cavo-convex form, adapted to receive a suitable stiffeningframe, and insuitable clips adapted to removably embrace the templebars of aspectacleframe and render the shield adjustable thereon.

Referring to the drawings, Figure 1 is a perspective View of an ordinaryspectacleframe provided with ashield constructed in accordance with myinvention. Fig. 2 is an inner perspective View in detail of a modifiedconstruction of the guard or shield detached. Fig. 3 is an outerperspective view in detail of the same; and Fig. at is a similar View asFig. 2, illustrating a modified means for the guiding-clips.

Like numerals of reference indicate like parts in all the figures of thedrawings.

. 1 represents a spectacle-frame, and 2 the temple-bars, all of theusual construction.

3 represents the shield, formed of celluloid, or, preferably, of light,sheet metal, as copper, brass, or steel, and pickled or otherwisetreated to give it the desired color, said shield being preferably of aconcavo conveXed shape in crosssection and formed with a square frontend. The form of the guard may be preserved. by a T-shapedstiffeningframe 4, the T end of which lies transverse the shield and isriveted or otherwise secured thereto a shortdistance in the rear of thefront edge thereof, and is bent into an L. shape in cross-section,forming an inwardly-projecting flange 5, from which are struck up a pairof forwardly-projecting parallel tongues or clips 6, adapted to embracethe hinge 7 of the spectacle-frame, for the reception of which the frontedge of the shield is notched or cut away, as at 8. When astiffening-frame, as at, is used, a tongue 9 is formed upon the upperedge of the shank portion of said frame, and said tongue is bentoutwardly and upon itself and passed through an opening 10, formedopposite the tongue, in the shield, which tongue is bent in the form ofa hook and adapted to embrace the adjacent temple-bar of thespectacle-frame. This is one form of shield, and from the, constructiondescribed it will be apparent that the shield may be adjusted on thetemple-bar so as to project more or less beyond the lenses, thusshutting out all side light and consequent reflection, and may beapplied and removed with facility.

As shown in Figs. 2 and 3, I may omit the T-shaped stiifening-frame 4:and form the hooked tongue 9 by striking the same directly from themetal or material from which the shield is formed, and so also may theclips 6 be thus formed, the same being constructed by simply slittingthe front edge of the shield longitudinally and laterally, and bendthese portions inwardly to embrace the temple-bars in rear of the hingesand be supported and guided thereby.

In Fig. i I vary the construction by fornr ing the recess 8 in the frontedge of the shield, and in mounting inwardly of the same a me tallic Ushaped plate 12,tl1e opposite branches of which are bent to form atemple-bar, embracing flanges or clips 6, said plate being riveted orotherwise secured to the shield, as at 13.

Having described my invention, what I claim is- 1. An opaque shield forspectacles, provided with a "notched front end, and means, as described,for securing the same to the frame thereof, substantially as specified.

2. An opaque shield for spectacles, provided with a notched front end,and means, as described, for adjustably and removably connecting thesame to the frames thereof, substantially as specified.
